Embodiments of the present disclosure provide a method and device for establishing backup path, a method and device for selecting backup path. The method comprises a first node in a first IGP domain receiving a response message of successful establishment of a main path from a second node in a second IGP domain through the main path; the first node obtains path information of the main path from the response message; the path information of the main path includes at least SRLG information of a link composing the main path; the first node establishes, according to the path information of the main path, a backup path between the first node and the second node; the SRLG information of a link composing the backup path is different from the SRLG information of the link composing the main path.

The invention discloses an intelligent environment management system based on the Internet of Things. The system comprises a dust concentration detection module, an oxide detection module, an environment parameter detection module, a noise comparative analysis module, an environment parameter storage database, a particle content analysis module, a data pre-screening processing module, a managementcloud server, an intelligent display terminal and a mobile dust suppression mechanism. According to the invention, whether the dust content and the temperature in the factory reach the explosion danger degree under the combined action can be comprehensively analyzed, and a mode of combining software and hardware is adopted; the mobile dust suppression mechanism is controlled to move to the position of the detection sub-region of which the predicted explosion danger coefficient is greater than a set predicted safety explosion danger coefficient threshold value, so the dust suppression operation is realized, and the explosion risk is reduced; whether the working environment meets the personnel office environment requirements or not can be judged through the statistical working environment matching suppression system, the environmental conditions in the personnel working environment can be visually displayed and analyzed, and the detection accuracy is high.

The present invention provides a photovoltaic module lamination process, including the following process flow: ① providing a photovoltaic module and a laminator for laminating the photovoltaic module, the laminator is provided with a heating plate, and the photovoltaic module There is a self-heating plate on the top; ②Set the lamination parameters on the laminator, and when the temperature of the heating plate and the self-heating plate reaches the specified temperature, put the photovoltaic module into the laminator and close the cover; Vacuuming operation between the layers; ④Then pressurize the upper chamber of the laminator, press the self-heating plate to the top of the photovoltaic module, and the self-heating plate and the heating plate simultaneously The photovoltaic module is heated; ⑤ After lamination, the lower chamber of the laminator is inflated, the upper chamber is evacuated, the upper cover is opened, and the photovoltaic module is taken out, and the lamination is completed. Such setting effectively controls the heating temperature of the photovoltaic modules at different stages, shortens the lamination time of the photovoltaic modules, and improves the production efficiency.
